IMPROVEMENT IN SOLDERING-TOOLS.

Specification forming part of Letters Patent No. 149,516, dated April li, 1874 application filed July 3, 1873.

To all whom it may concern:

Be it known that I, DECATUR WEIDLEY, of the city and county of Philadelphia, and State of Pennsylvania, haveinvented a new and useful Improvement in Soldering-Irons;

. and I do hereby declare the following to be "which- Figure l is a side view of the device embodying my invention. Fig. 2 is a central longitudinal section in line w fr, Fig. 3. Fig. 3 is a similai1 view in line y y, Fig. 2.

Similar letters of reference indicate corre spending parts in the several figures.

This invention relates to a soldering-tool of the order known as gas-heated; and consists in pipes arranged on the outside of the tool, and extending toward the point thereof', so as to heat the tool and utilize the llame, after the manner of a blow-pipe. It also consists in a chamber, in combination with a plug and cap, the induction-pipes, yand the eductionpipes. It also consists in the construction of parts for holding the tool or point, and permitting the removal thereof.

Referring to the drawings, A represents the tool or point, and B the handle thereof, which are attached to each other by the connection C. This connection is hollow, and divided transversely by a plate, a, which leaves two chambers, the forward one of which receives the inner end of the tool or point A, and the rear chamber constitutes a receptacle for gas or other fluid employed'for heating the tool A, as will be hereafter stated. An opening is made in the connection G and inner end of the tool, and through these openings is passed a screw-bolt or pin, D, on which are fitted tighteningnuts E, which, together, serve to hold the tool orpoint firmly in place, yet permit the ready removal thereof from the connection C whenever desired or required.

The handle B is hollow, and through the same is passed two pipes, F F, one of which communicates with a gas supply, and the other with an air-blast, and both pipes are attached to a plug, Gr, which is arranged at the forward end of the handle B and rear of the connection C. On the plug Gr is iitted a perforated conical cap, H, which thus projects in the rear chamber J of the connection C, and its dimensions are such that a space, d, is left between said cap and the plug Gr. The pipes yF communicate with the space d by means of openingsbcformed in the plug G, which openings may be said to be continuations of t-he said pipes F. Krepresents pipes, one or more, which project from the connection C, and communicate with the chamber J, which pipes eX- tend forward, and are curved or bent toward the pointed end of the tool, the opening of the pipes being likewise toward the pointed end.

The operation is as follows: The -gas and air blast being let onf7 each flows through its respective pipe F, and the two unite at or about the perforation ofthe conical cap H, so that the two volumes commingle, or are mixed, in which state they ll the ehalnber J, then escape with a uniform pressure through the pipes K K, and are then directed in a blast against the tool A.

On ignition of the compound fluid, it is evident that the flame thereof will be driven against the tool A, so that the latter will be subjected to the action of every particle ofthe llame, and thus be heated in a powerful and uniform manner, the heating qualities of the gas being increased by its union with air, in the manner stated.

the pipes, as stated, is that the flame may be .directed against the solder or article to be soldered after the manner of a blow-pipe. The dame first impinges against the tool, as at h, thus heating the same, and is then directed along the surface of the tool toward and beyond its extreme point, so that the flame reaches every portion of the working part of the tool, and thoroughly heats the same.

For heavy work, the employment of the heated tool and of the flame will be found of great service.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the tool A., of the pipes K, arranged on' the outside of the tool, and toolA, constructed with the plate a., f'ormI and projecting toward the point thereof, so ing the rear chamber J, and the front recess that the tool will be heated andthe llame ma y for the reception of the rear of the tool, and be used after the manner of a blow-pipe, as provided with the bolt D, passing through the herein set forth. connection and tool, and the nut 0r nuts E, 2.
